- The object of my invention is to provide a variable speed device of the cone and turnbler type with means for throwing the drivenshaft into driving relation with the- ,1'5 driving shaft, simultaneous with the. disengagementof the tumbler gear from any one of the members of the cone. 4 1 V Another object of myinvention' is to pro-.

vide a 'clutchactuating frame inconnection 20 with the tumbler lever, whereby the tumbler.

lever will actuate the frame during its swinging} operation in" bringing its tumbler glear into and out of 'enga ement with one o'f t members of a cone 0 gears with means V the tumbler.

Another object Of my invention is to proa compound tuma cone of gears..
